In the drawings I have shown the split spring-rings E as being laminated; but any form of spring which will retain the rollers in contact with the annular bearing-face of the casing will answer the same purpose, and various other details of construction which would readily suggest themselves to a skilled mechanic may be employed without departing from the spirit of my invention.

In the present application I do not claim the means for preventing the end thrust of the journal, as that forms the subject-matter of a divisional application,Serial No. 697,625, filed November 29, 1898.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States,

1. Ina roller-bearing, acasing formed with an internal annular bearing-face, an annular series of cylindrical rollers, and a concentric sleeve encompassed by said series of rollers and having a roller-bearing surface of a less length than the roller-bearing face of said casing, substantially as and for the purpose set forth.

2'. In a roller-bearing, acasing formed with an internal annular bearing-face, an annular series of cylindrical rollers,a concentric sleeve and spring-rings interposed between said sleeve and rollers, substantially as and for the purpose set forth.

3. In aroller-bearing, acasing formed with an internal annular bearing-face, a concentrically-grooved sleeve, a spring-ring seated in said grooved sleeve, and a series of bearing-rollers interposed between said springring and sleeve and the bearing-face of said casing, substantially as and for the purpose set forth.

4. In a roller'bearing, acasing formed with an internal annular bearing-face, a sleeve having an external bearing-face of a'less area than the bearingface of said casing, and formed with annular parallel collars, and a series of bearing-rollers confi ned between said collars and sleeve, and said casing, substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 21st day of September, 1898.
